By the way, does the Zupreem bird food make your igs poop have color? The rep cal does, and I am not sure if it is good, it makes when he poops in the water that the water turn kinda bluish. But I have not seen on forums that says it is bad. Perhaps it is edible and safe food dye? So this is OK and I can still feed the rep-cal, and is the bird food better?
